Wichita ? A police officer used justifiable force in the fatal shooting of a man who chased another officer with a knife, Sedgwick County Dist. Atty. Nola Foulston said.

Steven McCullough, 42, was shot three times March 18 in the Wichita apartment building where he lived. McCullough, who had paranoid schizophrenia, told police he wanted to die but did not say why, according to Foulston’s report.

Foulston said McCullough had called 911 claiming someone was in his apartment. Officers found McCullough in his living room holding a knife.

He refused to drop the knife, telling the officers, “You’re gonna have to shoot me if you want me to put it down,” according to the report.

McCullough put the knife on a table and sat down, then came toward the door at the officer’s request, according to the report.

The report said the officer sprayed tear gas, but McCullough grabbed the knife and chased the officer. Another officer shot McCullough as he pursued the first officer, the report said.
